Alloy steels comprise a wide range of steels having compositions that exceed the limitations of Si, Va, Cr, Ni, Mo, Mn, B and C allocated for carbon steels. These steels contain elements such as chromium, cobalt, nickel, etc.
In comparison with carbon steels, alloy steels are a lot more responsive to mechanical and heat treatments. Alloy steels can be subjected to unique melting and deoxidization processes for specific kind of applications.
AISI 9310 alloy steel is a low alloy steel containing molybdenum, nickel and chromium. The following datasheet provides an overview of AISI 9310 alloy steel.

Fabrication and Heat Treatment
AISI 9310 alloy steel is usually tempered at 149°C (300°F).
AISI 9310 alloy steel is annealed at 857°C (1575°F) and then slowly cooled in the furnace.
Conventional methods are used to cold work AISI 9310 alloy steel that has good ductility in the tempered and hardened conditions.
AISI 9310 alloy steel has good weldability characteristics as it can be welded by a standard process along with the usage of established welding methods.
AISI 9310 alloy steel is forged at 1191°C (2175°F) down to 927°C (1700°F).
AISI 9310 alloy steel can be readily formed by conventional procedures as this steel has good ductility even in the tempered and quenched condition.
AISI 9310 alloy steel can be machined by conventional methods and good results are obtained when this alloy steel is machined in the tempered or annealed condition.
AISI 9310 alloy steel is carburized by being heated at 927°C (1700°F) and then oil quenched. This alloy steel is then normalized at 899°C (1650°F), followed by air cooling and then tempering at 149°C (300°F).
AISI 9310 alloy steel can be hardened by cold working or by thermal treatment and oil quenching.
